stderr, and thus be captured in a log ﬁle. Any console output will be garbled.

• When a startup script returns an exit code of

3, /sbin/rc can display a speciﬁc message on the

console prior to rebooting the system. This is achieved by creating a text ﬁle named

/etc/rc.bootmsg

containing the text to be displayed to the console. Note that

/sbin/rc

deletes this ﬁle after displaying the message, so startup scripts need to write this ﬁle each time a

speciﬁc message is required to be displayed on console prior to reboot.

RETURN VALUE

The return values for startup scripts are as follows:

0 Script exited without error.

1 Script encountered errors.

2 Script was skipped due to overriding control variables from

/etc/rc.config.d

ﬁles, or for

other reasons, and did not actually do anything.

3 Script will automatically reboot the system.

4 Script exited without error and started a process in background mode.

>4 For return values greater than

4 the action is same as return value 1, script encountered

errors.
